We present a system that displays an image of any metal structure in a scene by the use of microwave radiation from a cavity resonator in a 10-GHz frequency band. An 80 mm × 80 mm mushroom-like electromagnetic band gap (EBG) structure was arranged, designed, analyzed, and integrated with an X band monopole antenna and the designed EBG monopole antenna has ∼2-GHz bandwidth. Meanwhile, a cubic cavity resonator is constructed and an EBG grounded monopole antenna is located on one wall of the cavity resonator to create a narrow band radiation. The formed narrow band radiation from the cavity resonator reaches to the metal structure located in the scene. Backscattered radiation collected by a 8 to 12 GHz waveguide receiver that is located near the cavity to scan the whole scene and sweep the waveguide throughout the resonator plane performs to gather various transmission values from a scene. These various transmissions from the cavity resonator antenna to the waveguide receiver were used for imaging. In addition, tunability of the designed EBG structure is studied and presented. The designed structure has advantages such as easy design and fabrication, high accuracy performance, and compatibility to the other frequency regimes. In addition, the designed EBG plane is based on RLC circuit theory, which enables us to understand the antenna performance and EBG structure. This system can be integrated with various areas, such as medical imaging, military applications, weapon detections, security imaging purposes, stealth technology, and other appropriate applications.

单极天线集成腔谐振器，用于微波成像

我们提出了一种系统，该系统通过使用来自10 GHz频带中腔谐振器的微波辐射来显示场景中任何金属结构的图像。布置，设计，分析并与X波段单极天线集成了80 mm×80 mm的蘑菇状电磁带隙（EBG）结构，所设计的EBG单极天线具有约2 GHz的带宽。同时，构造了一个立方腔谐振器，并且一个EBG接地单极天线位于该腔谐振器的一面壁上，以产生窄带辐射。从腔谐振器形成的窄带辐射到达位于场景中的金属结构。由位于腔附近的8至12 GHz波导接收器收集的反向散射辐射可以扫描整个场景，并在整个谐振器平面上扫过波导，从而可以收集场景中的各种传输值。从腔谐振器天线到波导接收器的这些各种传输都用于成像。此外，还研究并介绍了设计的EBG结构的可调性。该设计结构具有诸如易于设计和制造，高精度性能以及与其他频率范围的兼容性等优点。此外，设计的EBG平面基于RLC电路理论，这使我们能够了解天线性能和EBG结构。该系统可以与各个领域集成，例如医学成像，军事应用，武器检测，
